| 摘 要： | 介绍了一种基于最小方差综合鉴别函数的复合匹配滤波器的优化算法。这种优化算法将最小平均相关能量综合鉴别函数的迭代算法引入最小方差综合鉴别函数的设计中,不但可以识别带有附加噪声的旋转图像,而且减小了滤波器对样本识别的输出相关峰值波动,改善了滤波器的识别效果。计算机仿真结果显示,这种复合匹配滤波器在信噪比、相关峰尖锐度及鉴别率等方面都有一定的提高。

| Abstract: | An optimal arithmetic based on minimum-variance synthetic discriminate function was introduced.This optimal arithmetic introduced the iterative process of the minimum average correlation energy synthetic discriminate function to the design of minimum-variance synthetic discriminate function.It can not only recognize the rotated images that is added the noise but also decrease the fluctuation of output correlation peak value.The result of computer simulation shows that the signal-to-noise,the sharpness of correlation peak and the noise resistance of this composite filter are enhanced. |
